To measure the parasite clearance time in falciparum malaria patients treated with DHA-PPQ.\n2. To determine the efficacy of DHA-PPQ at day 42 post-treatment.\n3. To assess the in vitro susceptibility of P.falciparum isolates towards DHA and PPQ in Quang Nam Province.\n4. To compare genetic profiles of P.falciparum isolates with delayed and those with normal clearance times in order to identify potential markers of resistance;'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'minimumAge': '2 Months', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Age: from 6 months of age;\n* Fever (body temperature above 37.5C) or history of fever in the previous 24 hours;\n* Mono-infection with P.falciparum with parasite density between 500-100,000/µl\n* Written informed consent to participate to the trial.
